Plus: the binoculars are good and clear, and the focus for each eye can be adjusted individually. Good quality soft cover, outside it is made of a lighter material like Cordura. The backlight works well and you can't accidentally leave it on as it's a momentary button and not a power button. The range calculator ring is measured in arc minutes and is simple and accurate for objects smaller than 20 inches (read more about the range finder function below). The binocular itself is solid, looks well built and has a good coating/finish. The strap is padded in the middle and comfortable. The compass is displayed at the bottom of your field of view and is accurate (gives you bearing in degrees, not north/south). You have to press and hold the button to turn on the backlight. The distance calculator ring only works for objects smaller than 20 inches (larger and you do your own calculations) and you must rotate (or turn the binoculars upside down) to use it. Depending on the distance between your eyes, flipping the binoculars up or down will cause the rangefinder reticle to deviate from vertical, and there's no adjustment to rotate the reticle (apart from head tilt). Eventually, the reticle will focus with the correct lens focus, so you can't focus on the reticle and the object at the same time. The end result is that your left eye is focused on the object and your right eye is on the grid, slightly blurring your view of the object when trying to determine its range. In summary, binoculars are good and a compass is useful. The calculator ring is a great trick that really works. The reticle is useful once you're familiar with the Moa system, but it can definitely be improved in terms of focus and alignment.
